This is why the tornado grading scale needs to be changed…

The tornado had a gate-to-gate velocity reading of 260 MPH. Strong circulation could be detected up to 18,000 feet above ground level. Had this thing hit civilization it would have destroyed everything in its path. Thankfully it only damaged farmland. However, due to the way tornadoes are rated, this will only be an EF0/EF1.

So...why does the scale need to be changed?

Thing looks like a mini hurricane.

Not everything needs an official ranking or a scale, it was a catastrophic storm and it’s very sad what happened

He is saying the rating is based solely on damage not strength.

It would like a hurricane is cat 5 but gets rated as a cat 1 if it does no damage.

They really need 2 scales. Damage scale and strength scale.

Here’s another pic of it

You are confusing storms. This is from last night and was rated as F1, solely because it was in open farmland and no one was hurt or had major damage.

On a strength scale it was bigger than the ones that killed people yet rated much lower

What if the scale is biased against people of color?

I get why he's saying it.

Playing devil's advocate, if the science community is in agreement with the ranking based on strength and destruction, then why change it just because there was a massive tornado that didn't damage anything?

It would seem to reason that giving the higher ranking due to devastation makes sense.

Why should a strong hurricane that stayed out in open water get the same ranking as a Labor Day, Camille, etc., that actually wrecked shite?

Not everyone in the science community is in agreement.

The tornado in New Iberia not too long ago carved a path about 3 miles from my house, I'd say.

It destroyed the tall building at the hospital and then went into that subdivision behind La 87. My neighborhood backs up to that one.

How do you implement the strength scale when there won’t be uniform sampling of velocities? The only reason the gate to gate velocity was able to be sampled so well is because it was so close to the 88d. If this same tornado happened in a radar gap then no one would be saying this today.

I’m sure that the scale made sense back when they didn’t have the kind of reporting they do now. All they really had to go on was how much destruction it caused. But yeah, since they can now measure the tornado then it would make sense to change the scale.

Today I learned that the Fujita scale is primarily a damage scale.

That’s not necessarily a great method for rating them either because winds like that may not have translated to the surface. Going by damage allows the rating to be based on what was actually happening at the surface rather than hundreds or thousands of feet up. Radar estimated wind speeds are also impacted by how close the storm is to the radar site (i.e. the height of the radar beam).

The fact that the OP started this thread without even taking that into consideration has me extremely triggered.

I get why people think this but there’s no way to accurately measure surface level wind speed on every tornado. You can accurately and (mostly) easily measure damage for every tornado.
